Abstract (en)

Separation circuit 250 separates a systematic bit and parity bit from a received packet. Combination circuit 204 symbol-combines the separated systematic bit in this retransmission unit with systematic bits acquired in preceding retransmission units. Then, decoder 214 likelihood-combines the separated parity bit with parity bits acquired in preceding retransmission units and performs error correcting decoding on the symbol-combined systematic bit using the likelihood-combined parity bit as a check bit. This makes it possible to increase the reception level and error correcting performance, reduce the number of times retransmission is carried out until all errors are eliminated and thereby improve throughput. <IMAGE>
